TPS54331 VIN capability

Other Parts Discussed in Thread: TPS54331, TPS54360

TPS54331 is used as 24V to 5V conversion.

The motor is connected to same 24V line.

Therefore,glitch is added from the motor.

Is it a problem although Glitch is about 13ns(50V)? 

(It is not necessarily guarantee.)

Best regards,

Noda

    I don't have any data for that, but 50 V is well above teh absolute maximum even for a short time like 13 nsec.  I would recommend clamping teh input voltage to below the absolute maximum TPS54331 voltage.  You could consider using TPS54360 (60 V max) as an alternative.
